If it snows tomorrow, the probability is 0.5 that John will practice his trumpet. If it does not snow tomorrow, there is only a 0.4 chance that John will practice. Suppose the chance of snow tomorrow is 60%. What is the probability that Justin will practice soccer this evening?

The probability that Justin will practice soccer this evening is 16%.

Step-by-step explanation:

The probability that John will practice soccer is given by the product of the probability that it won't snow and the probability that he'll practice soccer. This is shown below:

practice soccer = (1 - 0.6)*0.4

practice soccer = 0.4*0.4

practice soccer = 0.16

The probability that Justin will practice soccer this evening is 16%,

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

part a

x     y

0     8

1     7.5

2     7

3     6.5

4     6

5     5.5  

for every hour i deducted .5 inches from the length of the candle

part b

it is a function because for every x value there is only one y value

part   c

for every x value there is only one y value

x       y

0       8

1       7.6

2       7.2

3       6.8
